Description

The session will briefly cover what CQRS and event sourcing is and what benefits they provide over traditional architectures. We will then build a simple ASP.NET MVC 3 application that will use CQRS and Event Sourcing. We will use Ncqrs to provide the underlying platform and see how CQRS and Event Sourcing simplifies software design, improves scalability and maintainability and how they fit into an ASP.NET MVC application.

The Discussion

Marcel Popescu

Fantastic video... thank you. I've been trying to get started with CQRS, but never understood how all the parts work together. This clarified it a lot.

One question: I want to write a multiplayer game (text-based, turn-based) and I need a timer (the players have a limited time to decide on their move). I can probably figure out a way to generate commands each seconds, but how do I use the framework to retrieve all the appropriate aggregates that are supposed to handle the "clock tick" command? I can't wrap my head around this. (I understand how a command will retrieve one aggregate, but I will have multiple ongoing games, and all of them need to find out if the move time has expired.)
